In Database section, users can access directly to the database to know how it looks like. As well, users can order the data and decide how many entries they want to be displayed.
In Data Visualization section, users can create some graphics from the available variables(features) on the database.They must choose a variable for the x axis and other one for y axis using the input windows displayed. Moreover, if users want to deflate the public revenue(ingresos), as the theory says, they must choose the base year to do it and the app will do the operation automatically. In this case, users can use the deflated variable to creat a graphic as well.
